What process describes the conversion of carbon dioxide and water into glucose and oxygen?

The process of converting carbon dioxide and water into glucose and oxygen is known as photosynthesis. This biological process primarily occurs in the leaves of plants, where chlorophyll captures sunlight. The light energy is then used to transform carbon dioxide, which plants absorb from the atmosphere, and water, which they take up through their roots, into glucose. The glucose serves as an energy source for the plant, while oxygen is released as a byproduct into the atmosphere, which is vital for the survival of aerobic organisms, including humans.

Photosynthesis is crucial for life on Earth as it is the foundation of the food chain; plants produce their own food and provide energy for herbivores, which in turn support carnivores. This process significantly contributes to the planet's oxygen supply, making it essential for maintaining the balance of gases in our atmosphere.
